Well... is it ever hard to desire only God! I don't think I'm making much progress there. I think if God was truly my only desire, I'd spend a lot more time talking with Him and reading the Bible and trying to grow with Him... instead, I find myself reading other books and playing games and trying to find other things to distract myself.
I don't believe that it is possible to force yourself to desire only God. I believe you must go through a process of discovering how much you need God over everything else and how much He desires you. Then, when we realize this, our perspective changes and we discover that only God can fill our true desires - the things that really matter.
I love this song by Tenth Avenue North. It is so beautiful and it is helping me realize the passionate love that God has for me. Then I feel loved and desired and wanted... and I think that is helping me to realize that God is all I need.
The song talks about a "bride," and most of the pictures seem to emphasize a female audience... but gender doesn't matter to God - He isn't human... so this is every bit as much for guys as it is for girls.
The next song by Addison Road reflects rather well my struggle to grasp who my God is.
"If you touched my face, would I know You?
"Looked into my eyes, could I behold You?"
What do I know of God? Of holy? Hearing this song and hearing someone else confess their struggles with discovering God encourages me and strengthens my resolve to dig deeper and learn more of God (who is holy).
I like this verse from Lamentations
"The Lord is my portion; therefore, I will wait for Him."
He is all that I need, so I will stand ready and wait for Him to give me His strength and power and all that I need in Him. How do I stay ready?
And from Ephesians 6:10
"Be strong in the Lord and in the strength of His might."
It is in His power that I can stand strong - my own isn't sufficient. Do I even have any?
Just some thoughts for me to think on more and [hopefully] some encouragement for you, too.
